GLOBE norms.

I Application filed September 13, 1924. Serial-No. 737,474,

My invention relates to lighting fixtures and particularly to a holderfor mounting a globe on a support or a suspended member. Lightingfixtures that are provided with a shade and a globe are often attachedto the husk by a number of screws or other separately-acting devicesthat require a number of manual operations inassemblingthe fixture.desirable feature, particularly in large fixtures, is to avoid suchstructures and to provide means comprising a small number of parts thatcan be easily and quickly operated to assemble and disassemble the globeand shade, so that all of the rather cumbersome parts may be securedtogether ina single operation.

In large globes there is usually some irregularity inthe size and shapeof the globe flange and there is also considerable con-, traction andexpansion by reason of heating and cooling of the globe, which causesbreakage of the globes where the flange is rigidly clamped. I provide aholder which adjusts itself tosuch irregularities and which permits alimited amount of expansion and contraction of the globe.

It is, therefore, one object of my invention to provide a holder whichshall attach all the parts in one operation, and which shall adjustitself to the irregularities in the globe and the shade. I

Anotherobject of my invention is to provide a globe holder which shallpositively unite the globe, shade and support, and shall provide meansfor the expansion and contraction of the globe after it is mounted.

Still another object of my invention is to provide a globe holder whichshall comprise a small number of parts and shall be inexpensive tomanufacture.

In the drawings constituting a part hereof and in which like numeralsdesignate like parts,

Fig. 1 is an elevational view partly in cross section, of a lightingfixture.

Fig. 2 is a top plan view of the keeper ring, and

Fig. 3 is a bottom plan view of the sup port.

Fig. 4 is an enlarged view of a portion of Fig. 1, showing in detail themanner of attaching the globe and shade.

The illustrated lighting fixture comprises a bell-shaped support or husk1 in which a lamp 2 is mounted and from which a globe 3 and a shade 4are suspended. The support 1 is provided with an inwardly turned flange5 and with an upturned circular flange or collar 6 that is provided withpins 7 spaced 180 apart. The shade and globe are supported by means of akeeper-ring, which comprises a collar member that is adapted to fit intothe upturned flange 6. The collar member 8 is provided with two L-shapedslots 11 that cooperate with the pins 7 for attaching and locking thekeeper-ring.

The collar 8 is further provided at its lower attaching the shade 4 tothe flange 5 by inserting pins 14 in the enlarged portions 15 of doublekey hole slots 13, and then turning the shade so that the pins are inthe small ends 13 of the slots. The globe 3 is then raised by means ofthe keeper-ring, and the pins 7 are entered in slots 11. By turning thekeeper ring, the pins are locked in notches 16 or 17, as the case maybe, accord ing to whether the shade or globe alone or both shade andglobe are mounted. The

springs 12 bear against the glass globe to thereby unite the shade andglobe, but in such manner that irregularities in the globe flange arecompensated for by the springs 12, and a slight movement of the globe,by reason of its expansion or contraction, is

permitted. If desired, a washer 18 may be inserted between the globe andshade.

My invention thus provides means for positively holding the shade andglobe. The holder allows expansion and contraction of the glass parts aswell as a considerable variation in the size and shape of the glassflange of the globe, without causing it to break.

Although I have described-a specific embodiment of my invention, I donot wish to be limited thereto,- since my stru u e my be modified invarious ways. For example, a different type ofv spring, such as a coilspring, may be used in place of the spring that I have shown. Othermodifications will suggest themselves to those skilled in the artwithout departing from the spirit of my invention, the scope of which isdefined in the annexed claims.
